Orchard Audio has announced the launch of the Starkrimson 25 Mono Premium, the latest evolution in high-performance gallium nitride (GaN) audio amplification. Designed for audiophiles, professionals, and music lovers, it builds upon the success of its predecessor, the Starkrimson mono premium, with enhanced capabilities and refinements. Designed for audiophiles, professionals, and music lovers, the SK25 delivers an even cleaner signal path.
The design leverages cutting-edge advancements in gallium nitride (GaN) transistor technology, with the SK25 achieving a faster transient response and improved high-frequency performance. With its compact and versatile form factor it is said to be “optimized for high-resolution playback, to provides a transparent and immersive listening experience, whether used in home audio setups or professional sound environments”.
Improvements over the original Starkrimson mono premium include:
- Improved switching frequency – 1.1MHz, was 800KHz
- Improved damping factor – >600 @ 1KHz, was >550 @ 1KHz
- Wider bandwidth & improved phas shifts above 20KHZ
- Improved filter components
- Updated modulator and feedback circuits
According to Orchard Audio, “With its next-generation GaN technology, this amplifier comes closer to the ideal of flat wire with gain”
